Describes a simple way to demonstrate the principles involved in a drinking water plant. This demonstration developed for a general public lecture can be used in chemistry and biology courses for an ecological and environmental emphasis. (HM)

Investigates and presents evidence concerning the construct validity of the Test of Higher Cognitive Learning in Chemistry (THCLC), a 40-item multiple-choice test developed to provide assessment of first semester introductory college chemistry students' higher cognitive skills. (Author/GA)

Several common ideas were discernible in the plenary lectures of the fifth biennial conference on chemical education. Among these were: The decline in university and college enrollments and how to cope with them, how to prepare chemists for changing job markets, and how to improve scientific literacy. (Author/BB)

This symposium focused on the question: can colleges afford to continue offering high quality laboratory instruction at the undergraduate level. (Author/BB)

This session focused on the types of chemistry courses taught in the high schools and the financial support of high school chemistry labs. (BB)

Investigates the possibility of using audio-tapes for self-study courses in technical colleges. This article presents: (1) description of the electrochemistry course taught; (2) results of the assessment of student reaction to the course; and (3) conclusions. (HM)

Describes an oscillating chemical reaction, and discusses numerous parallels to it in research, such as in fibrillation of the heart, body-clock rhythms of animals and plants, the self-assembly of multicellular organisms, and certain stripes in volcanic rock. (GA)

Describes the intuitive approach used in general chemistry and points out its pedagogical advantages. Explains how to extend it to acid-base equilibrium calculations without the need to introduce additional sophisticated concepts. (GA)

Presents two demonstrations; one on Boyle's Law, to illustrate the gas law and serve as a challenging problem for the students; the other is a modified Color Blind Traffic Light demonstration in which the oscillating reactions were speeded up. (GA)

Investigates the effects of high school chemistry experiences on the use of Piaget's operative structures. Reports that students who took chemistry scored higher than those who did not on a test of Piaget's operative comprehension. (GA)

Discusses two different uses of information theory in chemistry to present entropy and chemical structure analysis. (GA)

This course is based on the premise that a sound base in the mechanics and electrokinetics of the dispersed phase is essential for an understanding of the macroscopically apparent behavior of such disperse systems. (Author/BB)

The opinion is presented that chemical engineering education seems to emphasize the professor's research and/or professional interests with little regard for the real needs of the student who intends to become a practicing engineer. (BB)

This article looks at the problems of revision of laboratory courses. While revision of the syllabus of experiments is expensive, it is necessary to keep it up to date. The nature, causes, and rates of change in practical courses are discussed. (BB)

Describes the use of atomic spectra that are excited in inductively coupled plasmas for the simultaneous or sequential determination of the elements at all concentration levels. (HM)
